American mathematician has a significant role and contribution in the modern
computer and computer architecture. The principal feature of von Neumann
computer includes the storage of program and data simultaneously. This architecture
describes an electronic digital computer that has parts such as Processing Unit and
arithmetic logic unit and processor registers. A counter instruction is used for storing
data and program simultaneously. The design of this architecture provides a much
simpler one than that of the Harvard architecture. This architecture has the capability
to save instructions as data and uses assembler, compiler, linker, loader and other
automated program to simultaneously in order to carry out the instructions. Some
high level languages such as LISP are used in this architecture, providing an abstract
machine independent way in order to manipulate the executable code at runtime.
This was a major development in the modern computer and thus architecture pave
the way for future computer architectures. The contribution of this of this great
mathematician is significant in modern computer and modern architecture.

Summary:
The evolution of the Internet is one of the greatest inventions that changes the world.
One of the networks that became the basis of the Internet is known as the
ARPANET. The concept was first published in the year 1967. ARPANET have been
developed in US, under the guidance of Advanced Research Projects Agency
(ARPA). In the year 1969, this network became the basis of the Internet and was
readily available for the rest of the world. The first message that was being send
using the Internet was a series of memos. This first message was written in the year
1962, by J.C.R Licklider. He was the first head of the computer program of the
DARPA, that started in the year 1962. The use of the ARPANET was useful and
significant. This is because the use of this networking marked the beginning of the
Internet, and spread all around the world. The modern Internet owes its success to
ARPANET, the first network that was used for Internet. This is a significant
development in the history of the development of Internet, thus is relevant in this
context as well. After the successful development of the ARPANET, various
computers were added to this network, in order to successfully use the ARPANET.
Week 4
Ethernet is an example of a Layer Two (L2) data link protocol that is discussed in the text.
Find and summarise a resource that describes the features and uses of ONE other L2
protocol that is not discussed in the text (i.e. NOT Ethernet).

http://www.erg.abdn.ac.uk/users/gorry/course/inet-pages/arp.html [Accessed 21 Sep.
2017].
Summary:
The Layer 2 protocols include a wide number of protocols along with Ethernet. These
include the Address Resolution Protocol (ARP), High-Level Data Link Control
(HDLC), IEEE 802.11 WiFi, IEEE 8-2.16 WiMax, Point-to-point Protocol (PPP). The
Address Resolution Protocol has been discussed below. The ARP is a protocol that
is used to map the Internet Protocol address to the physical address of a machine,
which is recognized in the local network. Four types of messages are send by the
ARP. These are the ARP request, ARP reply, RARP request, RARP reply. When an
incoming data packet, that is destined for a host machine arrives at a gateway, it
asks the ARP program to provide the MAC address which matches with that of the IP
address. The ARP looks in the ARP cache for the address and converts to the right
packet length, before sending it. However, if there is no entry found, for the IP
address, ARP broadcasts a request packet in a special format that is compatible for
all machines. The ARP is one of the most important layer 2 protocols and maps the
IP address to the MAC address successfully.
Week 5

penetrating into the military network. This was one of the biggest military threats that
the world had ever witnessed. Gary wished to seek information regarding the UFOs.
In this quest of acquiring knowledge, he thought of getting access to the websites of
NASA directly. He hacked into 97 US military and the website of NASA. He deleted
few essential files. He was soon found guilty of hacking into the military website and
the website of NASA. Along with deleting essential files, he also shamed the military
website. He was able to shut down 2000 military computers for 24 hours. Gary was
accused of hacking, copying confidential data, manipulating accounting files, and
copying various passwords on his own computer. The US authorities faced a hige
loss sue to this hacking and they estimated the cost of tracking and correcting the
issues was over $700,000. Thus, Gary could be cited as one of the most malicious
hackers that the world of computer had ever witnessed. The loss he caused to the
websites of NASA and the US military, took a huge time to be recovered.

Summary:
Data mining could be defined as the practice of using large pre-existing databases, in
order to generate new information, from the existing ones. One of the areas of
business that uses the technology of data mining includes the retail sector. The
retailer sector segments the customers into RFM groups. This refers to the
segmentation of the customers using Recency, Frequency and Monetary factors.
The retail sector uses the technology of data mining in order to classify the
customers in these groups. This segmentation is done in order to offer different
promotions and discounts to different set of customers. The customers who are loyal
customers and have a buying history with the particular brand are given more
discounts and loyalty offers. However, the new customers are also given high
discounts in order to ensure that these customers are attracted towards the particular
retail brand. Thus, with the use of the technology of Data mining the retailers are able
to understand the buying pattern of the customers. Along with the usage of data
mining in the retail industry, the other areas of application of data mining include the
e-commerce, supermarkets, Facebook, crime agencies.

Summary:
The use of information system and information technology has been a boon for the
society and the world. However, there are certain negative effects of the IS/IT
systems, that have a negative impact on the society as well as humankind. One of
the major negative impacts of the society is the loss of jobs of the people in the
society. With the increase in the use of IT/IS, the manual labour has been replaced
with digitalization. Moreover, the economic consequences of the extensive use of the
IT/IS systems include loss of income, loss of social status as well as loss of self-
esteem. This is one of the major negative effects of IS/IT. Another negative effect of
the extensive use of IT/IS is the loss of real life socialization. With the increase in the
use of the social media, and social networking sites, the people connect to other
people all over the world. However, they fail to connect with people in the real world.
Thus, the virtualizations have overtaken the real life relations. These are some of the
negative effects of the extensive use of the information system and information
technology.
